To a/Z whom it may concern: v

Be it known that I, JOHN S. FREY, a citizen of the United States of America, and a resi dent of Glendale Station, Queens county,` in

the State of New York, have invented a new and useful Improvement in Oil-StoveBurner Oups, of whioh'the following is a specification.

This invention relates to what are known as blue-flame oil-stoves of thatspecies in which an annular burner-cup containing a -short incombustible wick or lighting-ring is combined with superposed combustion-tubes concentric with the burner-cup and with each other and adapted to be removed from theV burner-cup and replaced .thereon when the oil is ignited. Such combustion-tubes areV oommonly'held concentricall-y within an opaque drum of sheet metal, and the latter is provided with a cold handle by means' of which the drum and combustion-tubes asone partare conveniently handled. As the drum conceals' the combustion -tubes from view, some means to facilitate locating them upon their seats, forming part of the burner-cup, is desirable. Various devices for this purpose have been proposed. I have discovered that by a very simple change in the construction of the burner-cup itself the ordinary combustion-tubes may be seated with the utmost facility, even when they are handled by an inexperienced person.

The present invention consists in a burner-y cup constructed as and for the purpose above indicated and in its combination with superposed combustion-tubes held within an opaque drum.

A sheet of drawings accompanies this speci- Y Like reference letters and numbers refer to like partsin both figures. E

The improved annular burner-cup (shown at A in Fig. 1 and segregated by Fig. 2) is or may be of any known or improved construction, comprising concentric horizontal shoulders or seats l and2 for the respective combustion-tubes a andv h of a blue-flame oilstove, concentric walls or curbs 3 and 4 at theperimeter and inner circumference of the burner-cup, respectively, and an annular depression or trough 5 midway between said curbs to hold the short incombustible'wick or lighting-ring B.

The outer lcurb 3 is made higher than the innercurb 4,'as shown in Fig. 1, and the latter, 4, terminates in an inwardly-projecting f horizontal flange 6, forming a level-surface upon which the lower edges of the combustion-tubes o, and b (either or both) may slide from any'position in which they may strike the same when they are lowered upon the burner-cup to their positions of rest upon their seats land 2, as illustrated by full and dotted lines in Fig. l..

The burner-cup'A ispreferably and oonveniently supported and supplied with oil by a Y-shaped coupling-piece 7, permanently attached to the burner as part thereof and inl communication with said annular trough 5 at bottom, and a perforated diaphragm C is held in place within the burner-cupbeneath the inner combustion-tube seat 2.

The combustion-tubes d and b are centrally supported within a sheet-metal drum D,which may be of any known or improved shape and proportions and is provided with the customvary cold handle c.

The width of the level-snrface-lforming flange 6 may be increased to any desired eX- tent that will not interfere with the function of the central airfpassage 8, and other like.

per extremity of saidinner ourb,substantially oireum ference of the burner-cup, and a levelas hereinbefore specified.

2. In combination with a pair of combustion-tubes supported within an opaque drum and movable therewith, an annular burnercup having horizontal seat portions upon which the lower edges of said combustion- .tnbes rest when in place, a curb extending around the perimeter of the burner-cup and surrounding the outer tube when said tubes are in place, a curb of less height than the curb first named extending around the inner surface-forming horizontal fiange projecting inwardly from the upper extremity of the curb last named, whereby said combustiontubes are adapted to slide into place upon their respective seats, substantially as hereinbefore specified.
